What can be done with Aatrox?

We all know he's a flawed champion, but I think there's actually a lot that can be done with his kit and theme. What really makes him a clunky champion to play seems to be his Q, the cast time is too long, the knock up too hard to land, the damage not very high... But what if we changed it into a more functional ability? Say his Q instead made him dash in a target direction, holding his blade off to the left side of his body as he dashed, and ending his dash with an upwards strike. The ability would only deal damage to enemies either directly in front of Aatrox, or just to his left. Enemies hit by his blade are cleaved for a % of their armour for a few seconds, while hitting an enemy with his body increases Aatrox's attack speed for a few seconds. Lastly, if the target is **already ** affected by a form of cc, (such as the slow from his w), and the target is at the end of his dash, his upwards strike will knock up the enemy. Any thoughts on what can be done on this forgotten champion?
